5 Pro Toning Moves for Every Bathing Suit Style

When stars such as Taylor Schilling and Hilary Rhoda want to get that long-and-lean shape, they call on "body designer" Katherine Greiner, who says that with the proper moves, "you can absolutely change the shape of your body." Here, she shows us how.

Here's the deal: After a harsh, terminally cold winter, it's about time we do a hard lean in to summer. Emphasis on the lean. And while warm weather dressing has its plus sides—no more dance floor-adjacent jacket pileups for at least six months—it also has its pitfalls: scantily-clad eeee'rything. But don't worry; we saw this coming. As promised in the June issue of ELLE, on newsstands in select cities starting May 13, and nationwide on May 20, celebrity trainer Katherine Greiner—who has worked with sinewy stars such as Orange is the New Black's Taylor Schilling and supermodel Hilary Rhoda—came up with five area-specific moves to get you bikini-ready. And once you've mastered the moves, shop our five favorite silhouettes for this season of swim.

The Pro Tip: Do at least 20 reps of this move (shown here from both the front and back) and feel free to add 2 or 3 lb. weights to increase difficulty. The idea is to fatigue the muscles, which might take up to 45 reps.

The Pro Tip: Beginners should aim to perform this move continuously for a minute; more advanced fitness buffs should aim for two minutes. When you are extending your leg out and up, keep the foot pointed to engage muscles from your hips down to your calves.

The Pro Tip: The balance required is the ultimate testament to core strength. Once you've got the transition down pat, experiment with longer and shorter pulses. Keep your lower tummy taut and really focus on the oblique muscles, which are responsible for keeping your waist whittled and contracted.

The Pro Tip: Most of us focus on toning the glamour muscles—the ones visible in the mirror—but if Kate Bosworth's backside at the Met Gala was any indication, there's something to be said about taut and tight shoulders. Greiner recommends two moves to strengthen everything from the lumbar muscles to the upper glutes. Extra points for concentrating on contracting, releasing, and lengthening all of the muscles that are conditioned to sitting in a desk chair all day long.

The Pro Tip: What's a "thut," you ask? It's when your butt and your thighs form a united nation. To lift and separate the two, focus on getting up and under the big glutes to target ancillary muscles that are often underused. Instead of counting reps, aim to do this move (and any of the others) until you feel as if you can't go on. And then do one more. You know, because you're worth it.
